# How to compare Coles, Woolworths and ALDI prices

Three supermarkets, three websites, different pack sizes. Here is how to put them in one table with unit prices.

**Short answer**

Run the **Coles, Woolworths & ALDI Scraper** with search terms and all three stores. Each row has price, was-price, unit price, special flag and stock, so you can compare per 100g or per litre.

## A real use case

A budgeting blog publishes a weekly basket comparison. Every Wednesday they search 25 staples across the three stores and publish the cheapest store per item using `unitPrice`.

## Step by step

1. **List your basket** as search terms.
2. **Select all three stores**.
3. **Optional:** specials only, or postcodes for store pricing.
4. **Run** and compare `unitPrice`.

### Input (paste into the JSON tab)

```
{
  "searchTerms": [
    "full cream milk 2l",
    "white bread",
    "eggs 12 pack"
  ],
  "stores": [
    "coles",
    "woolworths",
    "aldi"
  ],
  "maxItemsPerQuery": 10
}
```

### What you get back

```
[
  {
    "retailer": "aldi",
    "name": "Farmdale Full Cream Milk 2L",
    "price": 2.45,
    "unitPrice": 1.23,
    "unit": "1L",
    "onSpecial": false
  },
  {
    "retailer": "woolworths",
    "name": "Woolworths Full Cream Milk 2L",
    "price": 2.8,
    "wasPrice": 3.1,
    "onSpecial": true
  }
]
```

Trimmed example. Names and numbers are illustrative; your run returns real data with more fields.

## Tips

- Compare unit price, not shelf price. Pack sizes differ.
- Schedule it weekly; specials change on Wednesdays.

## What it costs

$1.50 per 1,000 products. 25 items × 3 stores × 10 results is 750 rows, about **$1.13**.

Plus a small per-run start fee. Apify's free plan includes monthly credit, enough to test. Check the listing for current pricing.
